Abstract
Micro-slip control of multi-disc clutches is effective for attenuation of vibration and smooth gearshifts in dual clutch transmission. This paper proposes a method to apply micro-slips on the clutches for gearshift process, which differs from the conventional lockup control. The vehicle powertrain is modelled as a six degrees of freedom dynamic system, including a hydraulic actuator model. Micro-slips of dual clutches are realised by a closed-loop feedback controller according to the control-oriented model. The controller is used to evaluate demands of the clutch torques and transform them to input currents for the hydraulic solenoid valves. Numerical analysis and experiment are preformed, and the results show that the effect of clutch micro-slips is significant in improving the shift smoothness and the drive comfort of the dual clutch transmission during gearshifts.
